Fine-particulate and ozone air pollution from fossil fuels causes 4-6 million avoidable deaths per year: 7-10% of all deaths worldwide. At an ~$11 million statistical value of life, this is a 44-66 trillion $/yr (38-56% of ~117 T$/yr global GDP) cost that appears nowhere in fossil fuel economics.

Coal-fired power plants killed at least 460,000 Americans between 1999 and 2020. Remember that as the EPA stops considering the benefits of halting air pollution. hsph.harvard.edu/news/particu...

Trump has been promoting air pollution denial since at least 2017. It’s taken different forms over the years, but the goal was always the same: to stop regulatory agencies from treating air pollution as a public health problem. The Trump EPA has now reached that endpoint.

China is now the leading clean energy powerhouse with the West falling behind. The transition is inevitable; the key question is where and how fast it happens. I look forward to discussing this in Davos next week at the World Economic Forum, facilitating a live-streamed session on electrostates.

Narrator: That's not how benefit-cost analysis works.

NEW: Coal-fired power generation fell in both China and India in 2025, for the first time since 1973. The drop came after record clean energy additions in both countries, and was the first time that clean energy was a major driver of falling coal power use.

The White House's withdrawal from 66 different international bodies will come back to hurt the US on climate and other issues, @markgongloff.bsky.social says www.bloomberg.com/opinion/arti...

Nobody ever said the death throes of the fossil age would be pretty or peaceful

The US stands alone in dismissing the problem of climate change.

📢 Yesterday, President Trump signed a presidential memorandum directing the United States to withdraw from 66 international organizations and treaties, including the UNFCCC and the IPCC. Read the full statement from David Widawsky, Director WRI US: bit.ly/3YrmIVx

NEW by @drsimevans.carbonbrief.org for @carbonbrief.org Analysis: World’s biggest historic polluter – the US – is pulling out of UN climate treaty "the largest contribution to the Earth’s warming climate by far" www.carbonbrief.org/analysis-wor...

The US is withdrawing from the UN Framework Convention on Climate Change, the treaty that has governed international climate diplomacy since 1992, per the AP: heatmap.news/sparks/us-wi... George H.W. Bush first signed the pact, and the Senate unanimously ratified. US has been a member since then.

The annual #EUAPredict forecasting competition has an average error rate of 23%. That's much better than pro carbon analysts (35.5%). Have you got a view as to where the EU carbon price could be at the end of 2026? Entries close 1700 GMT www.carbonrisk.world/euapredict-2...

I have been saying this for some time to students seeking career advice: the energy sector is one of the most exciting places to work with a huge transformation taking place right now. Electrification is a game changer and means a redesign of our energy system as we know it.

Venezuela has pretty great monazite / rare earth deposits so yeah that might be part of this

In news that should surprise no one…

Happy CBAM day for those that celebrate 🎉

The fires that tore across Los Angeles County nearly a year ago killed 31 people and destroyed more than 16,000 buildings. Angelenos are still learning the full extent of the damage

2025 has been a historic year for clean energy in UK, with renewable project approvals reaching a record-high 45 GW — nearly double of 2024. This surge was driven by an exceptional rise in battery storage capacity, which almost doubled to 28.6 GW, alongside strong growth in offshore wind & solar.

Mark Carney's approach to climate policy shouldn't be dismissed as a race to the bottom. A strong industrial carbon pricing mechanism will reduce emissions in the most efficient way possible, and at the lowest cost to households and businesses. www.carbonrisk.world/a-statement-...

Important discussion paper dropped today from ECCC on how to strengthen carbon markets in Canada, as part of the 2026 federal pricing benchmark review of federal and provincial industrial carbon pricing systems. Comments due by Jan. 30. www.canada.ca/en/environme...

In often hear people saying that command-and-control policies should be preferred over carbon pricing because they signal a stronger political commitment. But apparently, command-and-control policies can be reversed as well. So maybe not the strongest argument in their favor/against carbon pricing.

The New Zealand carbon price has slumped by around one-third since early November to ~NZ$37 per tonne CO2 (€18) after the government shattered market confidence in its commitment to climate policy. www.carbonrisk.world/new-zealands...

Climate change is already imposing costs on U.S. households ranging from $220 to $570 per year, according to a recent report. Households direct and indirect insurance costs account for ~50-60% of the impact from climate change. www.brookings.edu/articles/who...

Methane is thought to be responsible for nearly half of net global warming to date. Tackling this one super-pollutant is the fastest way to slow down the rate of warming in coming decades. Yet finance for methane abatement measures represented less than 2% of total climate finance flows.
